I didn't use it so much and not during a long moment, so I can't say if it is noisy. Using the intel GPU instead of the NVIDIA one could help I think.

For the fingerprint, I packaged libfrpint from https://github.com/iafilatov/libfprint and fprint_demo, with frpint_demo the figerprint is recognized, but some stuff has to be done with PAM to get the fingerprint feature with LightDM.
